Web metrics company Net Applications has estimated that IE9 accounted for about 38% of all versions of IE used last month, second only to IE8, which owned a 45% share of the Microsoft browser base.
Next week's IE update will be the first since Microsoft delivered a rush patch to stymie active attacks exploiting a bug. The Sept. 21 out-of-band update, which also included fixes for several other vulnerabilities, had been originally slated to ship two weeks later.
Another update, pegged "moderate" by Microsoft, will patch four flaws in Office's Excel spreadsheet. All still-supported versions of the suite -- ranging from Office 2003 to Office 2010 on Windows, and Office 2008 and Office 2011 on OS X -- will receive the update.
And Storms wondered what Microsoft would reveal next week about Bulletin 4, today's label for an update to the .Net framework within all versions of Windows. Windows RT's Bulletin 4 patch was rated "important," but fixes for all other versions, including Windows 8 and Server 2012, were pegged critical.
"Bulletin 4 could take the cake next week," said Storms. ".Net is so ubiquitous, used not only in software but also in Web services. And who knows where the bug is?"
Microsoft will release the six updates at approximately 1 p.m. ET on Nov. 13.
